Pictures circulating on twitter

Hey all, I’ve seen a couple of pictures circulating on twitter of “NHI recovered biologics” but I have not seen them in this sub yet. They are older but don’t seem to be AI generated. One is labeled figure 4 and the other figure 13. Have they been posted here yet or have they been posted and then later taken down? I believe you should be able to find them on twitter. They may have originated from 4chan but nonetheless they look like they could be something we should be looking at.
